This application is a divisional of U.S. patent application Ser. No.11/404,668, filed Apr. 14, 2006, the entire contents of which isincorporated herein by reference.

BACKGROUND OF THE INVENTION

This invention relates generally to hangers, and more particularly tohangers for supporting objects on one or more support rods attached toframing in a building.

Vertical support rods are often used to support objects in buildings,such as cable tray used for routing electrical “cable” (i.e., conductorsfor transmitting electrical or optical signals or electrical power). Onesuch type of tray is “wire basket” cable tray formed from wire membersextending longitudinally and transversely of the tray. The threadedsupport rods used to support such cable tray, sometimes referred to asall-thread rods, generally come in standard sizes, such as a 0.25 in.and 0.375 in diameter rod for lighter duty applications and a 0.500 in.and 0.625 in. diameter rod for heavier duty applications. The hangersused to support cable tray on these vertical rods come in a wide varietyof sizes and shapes. In conventional designs, the hanger is usuallyattached to a support rod by two nuts threaded on the rod above andbelow the hanger. To accommodate different rod sizes, the hanger has alarge opening to receive the largest rod size. The wide opening oftenrequires installing flat washers on both sides of the hanger. Theprocess of properly positioning both nuts (and the washers, if used) onthe support rod to secure the hanger in place is time-consuming andcumbersome. Reference may be made to U.S. Pat. No. 6,530,545 for oneexample of a prior hanger.

There is a need, therefore, for an improved hanger which facilitatesattachment of objects to a support rod, including objects such as cabletray, and more particularly “wire basket” cable tray.

SUMMARY OF THE INVENTION

One aspect of this invention is directed to a hanger adapted for hangingan object from a generally vertical support rod. The hanger comprises ahanger body having first and second sides, a first set of one or morehooks on the hanger body for receiving the support rod, and a second setof one or more hooks on the hanger body for receiving a portion of theobject supported by the hanger.

DETAILED DESCRIPTION

FIG. 1 shows several hangers of this invention, each generallydesignated 1, mounted on all-thread support rods R1, R2. The hangers areused to hang various objects, including “wire basket” cable tray of thetype indicated at 3 in FIG. 1. As shown, the cable tray 3 has a bottom 5and two upstanding side walls 7 for holding and routing electricalcable. The tray 3 is formed by a first plurality of generally parallelwire members 9 extending generally longitudinally of the tray, and asecond plurality of wire members 11 extending generally transversely ofthe tray. The longitudinal and transverse wire members are joined atcross-over locations or intersections 15.

Referring to FIG. 2, the hanger 1 comprises a hanger body 21 having afirst (front) face 23 and an opposite second (back) face 25 (FIG. 1). Afirst set of one or more hooks 27 extends from a first side 31 of thebody 21, and a second set of one or more hooks 35 extends from a secondside 37 of the body adjacent the first side 31. In the illustratedembodiment, the hanger body 21 is relatively thin, generally planar, andpolygonal in shape with a third side 41 generally opposite the firstside 31 and a fourth side 45 generally opposite the second side 37.However, it will be understood that the hanger body 21 could have othershapes without departing from the scope of this invention. The first setof one or more hooks 27 is shown as comprising two hooks (eachdesignated 27) which define a first elongate recess 51, and the secondset of one or more hooks 35 is shown as comprising two hooks (eachdesignated 35) which define a second elongate recess 55. Thehook-defined recesses 51, 55 are on opposite sides of a plane 57 definedby the hanger body 21 and have respective axes A1, A2 generally at anangle relative to one another. (By way of example, this angle may beapproximately 90 degrees, plus or minus 5 degrees to offset anyasymmetry or other features of the hanger to that it hangs at thedesired orientation.) The two hooks 27 of the first set have a first gap61 between them, and the two hooks 35 of the second set have a secondgap 65 between them. It will be understood that the number of hooks ineach set can vary.

The hanger 1 also includes first and second field-bendable tabs 71, 73projecting from the hanger body 21. In its factory (un-deformed) stateor condition, the first tab 71 projects from the fourth side 45 of thehanger body generally in the plane 57 of the body. Similarly, in itsfactory (un-deformed) state or condition, the second tab 73 projectsfrom the third side 41 of the hanger body, also generally in the planeof the body. These tabs are bendable along bend lines 71BL and 73BL,respectively, preferably generally adjacent and parallel to respectiveside edges of the hanger body. To facilitate bending, one or moreopenings (e.g., slots 81) may be provided along these bend lines.

In accordance with one aspect of this invention, the hanger 1 can beused with support rods having different diameters. In this regard, thefirst hook-defined recess 51 (see FIG. 2) preferably has a transversedimension D1 suitable for receiving a support rod R1 of a firstdiameter, and the second hook-defined recess 55 has a smaller transversedimension D2 suitable for receiving a smaller-diameter support rod R2.By way of example, each hook 27 defining the first recess 51 isgenerally J-shaped and has an arcuate support surface 87 with a diameterof about 0.390 in. for snugly receiving and cradling a 0.375 in.diameter rod R1. Similarly, each hook 35 defining the recess 55 isgenerally J-shaped and has an arcuate support surface 91 with a diameterof about 0.265 in. for snugly receiving and cradling a 0.250 in.diameter rod. Other dimensions are possible. A reinforcing rib 95extends along the length of each hook 27, 35 for added strength. Also,while the hooks are shown as generally J-shaped, they can have othershapes (e.g., channel-shaped).

FIG. 1 illustrates the use of the hanger 1 on two support rods R1, R2having different diameters. As will be observed, the orientation of thehanger 1 varies from one rod to the other so that the rod R1, R2 isreceived in the appropriate set of one more hooks 27, 35 sized for thatrod. The other set of hooks receives a longitudinally-extending wiremember 9 of the tray 3. The diameter of this wire member is typicallysubstantially less than the diameter of a support rod (R1 or R2). Forexample, the wire member 9 may have a diameter of about 0.20 in.

To use the hanger on the larger diameter rod in FIG. 1, the hanger isoriented so that the first set of one or more hooks 27 defining thelarger recess 51 receives the rod R1 and the second set of one or morehooks 35 defining the smaller size recess 55 receives a longitudinallyextending wire member 9 of the wire basket. The gap 61 between the hooks27 of the first set receives a single nut 99 threaded on the rod, andthe gap 65 between the two hooks 35 of the second set receives atransverse wire member 11 of the tray, if a transverse wire happens tobe positioned to be received in the gap. With the hanger 1 thuspositioned, the first tab 71 is bent down in a generally rearwarddirection, as shown, to prevent substantial lateral movement of the rodR1 relative to the hanger 1, thereby retaining the support rod in thefirst hook-defined recess 51. The second tab 73 is also bent in aforward direction to prevent substantial vertical movement of the tray 3relative to the hanger 1, thereby retaining the longitudinal wire member9 in the second hook-defined recess 55. The tabs 71, 73 can be bentmanually by hand or by using a suitable tool (e.g., screw driver orpliers). As used in this orientation, the smaller diameter rod R2 issnugly received in the first hook-defined recess 51, and the hanger 1 issecured in substantially fixed position on the rod R1 by the one nut 99and the bent first tab 71. The vertical position of the hanger 1 (andthus the elevation of the tray 3) can be readily adjusted by threadingthe nut 99 up or down on the rod R1.

To use the hanger 1 on the smaller-diameter support rod R2 in FIG. 1,the hanger is positioned such that the second set of one or more hooks35 defining the smaller recess 55 receives the support rod R2 and thefirst set of one or more hooks 27 defining the larger size recess 51receives a longitudinal wire member 9 of the tray 3. The gaps 61, 65between the respective hooks 27, 35 receive the nut 99 and anytransverse wire member 11, as described above. (For convenience, thegaps 61, 65 may have approximately the same width, e.g., 0.625 in.) Withthe hanger 1 in this position, the tabs 71, 73 are bent to retain thesupport rod R2 and longitudinal wire member 9 in respective hook-definedrecesses 51, 55.

The hanger 1 preferably (but not necessarily) has a feature whichfacilitates adjustment of elevation of the hanger (and the cable tray 3)on the support rod. In this regard, the gap 61 between the two hooks 27of the first set of hooks is sized and contoured to permit relativevertical movement between the hanger 1 and the nut 99 from a firstun-locked position (FIGS. 5 and 6) in which the nut is at a location inthe gap 61 in which it is freely rotatable on the rod, to a secondlocked position (FIGS. 3 and 4) in which the nut is at a differentlocation in the gap 61 in which it is prevented from rotation by contactof the nut with the hanger. The gap 61 between the two hooks 27 isdefined in part by a segment 105 along the first (generally vertical)side edge 31 of the hanger body 21 and in part by opposing (generallyhorizontal) edges 107 of the two hooks, namely, the lower edge of theupper hook 27 and the upper edge of the lower hook 27. It will beunderstood that the gap 61 could be defined in part by structures otherthan the two hooks 27. When the nut is in its locked position shown inFIGS. 3 and 4, the lower edge 107 of the upper hook 27 contacts theupper surface of the nut so that the hanger is supported at the desiredelevation on the rod R1.

As illustrated in FIG. 2, the vertical segment 105 along the hanger body21 is contoured to provide a nut-receiving recess 115 at a locationcorresponding to the stated un-locked position of the nut. This recess115 is defined by a channel 117 formed in the hanger body 21 extendinghorizontally inward from the first side edge 31 of the hanger body. Thechannel 117 has opposite side walls 121 and a base wall 123 spaced fromthe plane 57 of the hanger body on a side of the plane opposite the twohooks 27. The nut-receiving recess 115 could have other configurations.The arrangement is such that when the nut 99 is received in the recess115, corresponding to its stated un-locked position (FIGS. 5 and 6), itis free to rotate on the rod. After the nut 99 is threaded on the rod R1to the desired position, the hanger 1 is allowed to drop down to aposition corresponding to the stated locked position of the nut (FIGS. 3and 4) in which the lower edge 107 of the upper hook contacts the nut 99to support the hanger at the desired elevation, and in which a verticalsurface of the polygonal nut (e.g., one of the vertical faces of ahexagonal nut) contacts the vertical segment 105 of the first side 31 ofthe hanger body 21 to prevent rotation of the nut, thus locking thehanger at the desired elevation. The height of the hanger 1 can bereadily re-adjusted at any time simply by lifting the hanger to move thenut 99 into its un-locked position received in the channel-shaped recess115, rotating the nut to the desired elevation on the support rod, andthen lowering the hanger back down so that the nut is in its statedlocked position supporting the hanger.

The channel 117 formed in the hanger body 21 also functions as areinforcing rib to strengthen the area of the hanger body between thehooks 27, 35.

The gap 65 between the two hooks 35 of the second set is preferablyconfigured in the same manner described above. As a result, the sameadjustment procedure described above can be used when the hanger 1 is inan orientation in which the support rod R2 is received in the two hooks35 of the second set of hooks.

It will be apparent from the foregoing that the hanger 1 described abovehas numerous advantages. It can be installed quickly and easily withonly a minimal use of tools, and installation requires only one nut tobe threaded on the support rod. The hanger can be used with differentsize rods, and each size rod fits in a designated area (a recess definedby a set of one or more hooks) specifically dimensioned for that sizerod to provide better support. Also, the position of the hanger iseasily adjustable along the support rod simply by threading a single nutup or down on the rod. Further, the hanger is economical to manufacture.For example, the hanger described above can be formed (e.g., in astamping operation) as a one-piece member from sheet material, such as14-gage (0.075 in. thick) sheet metal.

In the particular hanger embodiment shown in the drawings, the two setsof one or more hooks 27, 35 extend from adjacent sides of the hanger.However, it will be understood that the two sets could extend fromopposite sides of the hanger. For example, referring to FIG. 2, the twosets could be located along the left and right vertical sides of thehanger body, and a suitable support device could be provided along thelower edge of the hanger body for supporting an object on the hanger.The support device could be of various types, including a bracket,threaded stud, or some other device. Also, the two sets of hooks on thehanger body could be sized for receiving threaded support rods of thesame diameter or different diameters.

Also, while the hooks 27, 35 shown in the drawings extend fromrespective side edges of the hanger body, it will be understood that oneor more sets of these hooks can be located toward the interior of thehanger body (i.e., off the perimeter of the hanger body) for receiving asupport rod. In this case, a nut-receiving recess (corresponding torecess 115 described above) can be provided in a face 23, 25 of thehanger body.

FIGS. 7 and 8 show a different embodiment of a hanger of this invention,generally designated 201, configured for supporting a cable tray 205,for example, from rods R1, R2. The hanger 201 comprises a hanger body209 having a first set of hooks 213 projecting from one side of thehanger body, and a second set of hooks 217 projecting from an oppositeside of the hanger body. The two sets of hooks 213, 217 are preferablysized for receiving support rods R1, R2 of two different sizes, as inthe first embodiment, although this is not essential. Field bendabletabs 221, 223 are provided for securing support rod(s) R1, R2 inrespective hooks. The hanger body 209 has nut-receiving recesses 225,229 for receiving nuts 231 on the threaded rods R1, R2, as describedabove. The hanger body 209 comprises an extension 235 at its lower endconfigured for connection to the cable tray 205. In the illustratedembodiment, the extension 235 is provided with a protruding threadedstud 239 which is adapted to be inserted through an opening in a siderail 241 of the cable tray. A nut 245 threaded on the stud 239 is usedto secure the connection between the hanger 201 and the cable tray 205.

This hanger 301 is similar to thehanger 201 of the previous embodiment except that the hanger body 305has an extension, generally designated 307, at its lower end which isconfigured for receiving the bottom portion of a side rail 311 of acable tray 315. In particular, the extension 307 is generally J-shaped.It has a stem 317 generally planar with the hanger body 305, a bottomportion 321 bent to extend laterally outward from the stem 317 forunderlying the side rail 311, and a lip 323 bent up from the bottomportion 321 to retain the side rail in place on the hanger. Theextension 307 may be integrally formed as one piece with the hanger body305, or it may be formed as a separate piece attached to the hangerbody.

FIGS. 11 and 12 show a different embodiment of a hanger of thisinvention, generally designated 401. This hanger 401 is similar to thehangers 201 and 301 of the previous embodiments, except that the hangerbody 405 has an extension, generally indicated at 407, at its lower endwhich is configured for receiving the box-section rail 411 of a cabletray 415. In particular, the extension 407 comprises a generallychannel-shaped formation having a top portion 421 adapted to overlie therail 411, a bottom portion 423 adapted to underlie the rail 411, and aconnecting web 425 having a vertical length which is only slightlygreater than the vertical depth of the rail 411 so that the fit of therail between the top and bottom portions of the extension is relativelysnug. A lip 429 is bent up from the bottom portion 423 to retain thebox-section rail 411 in place on the hanger 401. The extension 407 maybe integrally formed as one piece with the hanger body 405, or it may beformed as a separate piece attached to the hanger body.

FIGS. 13 and 14 show another version of a hanger of this invention,generally designated 501. The hanger is similar to the hanger 1 of thefirst embodiment, except that the hanger body 505 has a first set of oneor more hooks 507, and a second set of one or more hooks 509 located onthe interior of the hanger body, i.e., in an area inside the peripheraloutline of the hanger body 505. In the illustrated embodiment, thehanger body 505 is generally rectangular, with rounded corners, but thisshape may vary. The hooks 507 of the first set are formed by pieces ofmetal (e.g., L-shaped pieces of metal) struck from the hanger body 505to extend on one face 513 of the body generally adjacent a first pair ofopposite sides 515 of the body. Similarly, the hooks 509 of the secondset are formed by pieces of metal (e.g., L-shaped pieces of metal)struck from the hanger body 505 to extend on an opposite face 517 of thebody generally adjacent a second pair of opposite sides 521 of the body.The two sets of hooks 507, 509 are preferably formed to receive threadedsupport rods R1, R2 of different sizes, as described above in regard tothe first embodiment. The support rods R1, R2 are retained in respectivesets of hooks 507, 509 by field bendable tabs 525, 527, as in the firstembodiment. Also, a nut-receiving recess 531 is provided in the hangerbody 505 for receiving a nut 533 threaded on the rod R1 or R2 receivedin a respective set of the hooks 507, 509. As shown in FIG. 14, thehanger body 505 has only one such nut-receiving recess 531, but it willbe understood that two separate recesses could be provided, oneassociated with each set of hooks 507, 509.

FIGS. 15 and 16 show a different embodiment of a hanger, generallydesignated 601, for supporting a cable tray, e.g., a wire basket cabletray 603, or other object. The hanger 601 comprises a hanger body 605having a set of one or more hooks 607 which are vertically spaced forreceiving a threaded support rod R1. In the illustrated embodiment, thehanger body 605 is generally rectangular, but this shape may vary. Thehooks 607 (two are shown) are formed by pieces of metal (e.g., L-shapedpieces of metal) struck from the hanger body 605 to extend on one face613 of the body. A nut-receiving recess 613 is provided in the hangerbody 605 for receiving a nut 615 threaded on the rod R1 received in thehooks 607. The hooks 607 and nut-receiving recess 613 function in themanner described above in regard to the first embodiment. The hangerbody 605 has a field-bendable tab 619 at its upper end for securing therod R1 in the hooks 607. The hanger body 605 also has an extension 621at its lower end which is configured for supporting the cable tray 603.In particular, the extension 621 comprises an elongate bar 625 at thelower end of the hanger body 605 sized for spanning at least asubstantial portion of (if the not entire width of) the cable tray 603to provide stable underlying support. In one embodiment, the bar 625 isan angle bar, but other shapes may be used. The bar 625 is connected tothe hanger body by a connecting portion 631. In the illustratedembodiment, the bar 625 extends in a direction which is generally atright angles to the plane of the hanger body 605, but this angle oforientation may vary from ninety degrees to zero degrees. The extension621 may be integrally formed as one piece with the hanger body 605, orit may be formed as a separate piece attached to the hanger body.Optionally, the bar 625 may be provided with one or more field-bendabletongues 635 for securing the bar to wires of the cable tray 603.

FIGS. 17 and 18 illustrate a different hanger embodiment, indicatedgenerally at 701, for supporting a cable tray, e.g., a wire basket cabletray 703 or other object. The hanger 701 comprises a hanger body 705configured as elongate bar (also designated 705) which is adapted tounderlie the cable tray 703 in a direction extending horizontally andgenerally transversely of the cable tray. The hanger 701 includes afirst set of four hooks 709 (two vertically-spaced hooks at each end ofthe bar 705) and a second set of four hooks 715 (two vertically-spacedhooks at each end of the bar 705). The four hooks 709 of the first setare configured for receiving threaded support rods R1 of a first size,and the four hooks 715 of the second set are configured for receivingthreaded support rods R1 of a second size. In the illustratedembodiment, the bar 705 comprises a top wall 721 and first and secondspaced-apart side walls 723, 725 having end portions which project outbeyond the top wall 721. Two hooks 709 of the first set of hooks extendfrom each end of the first side wall 723, and two hooks 715 of thesecond set of hooks extend from each end of the second side wall 725. Afirst set field-bendable tabs 731 project up from the end portions ofthe first side wall 723 for retaining the rods R1 in the hooks 709, anda second set of field-bendable tabs 733 project up from the end portionsof the second side wall 725 for retaining the rods R1 in the hooks 715.The first side wall 723 has a first set of nut-receiving recesses 741for receiving nuts 743 threaded on rods R1, and the second side wall 725has a second set of nut-receiving recesses 747 for receiving nuts 749threaded on rods R2. It will be understood that only one set of two rodsR1 or R2 is used at any given time for each hanger 701, unless extrasupport is needed. The hooks 709, 715 and nut-receiving recesses 741,747 function in the same manner described in previous embodiments.Optionally, the top wall 721 of the bar 705 may be provided with one ormore field-bendable tongues 755 for securing the bar to wires of thecable tray 703. The hanger 701 in this embodiment is shown as fabricatedfrom a single piece of metal, but it will be understood that it could befabricated as separate parts secured together in a suitable manner.Further, the specific cross sectional shape of the bar 703 can vary, ascan the shapes and positions of the hooks 709, 715 and tabs 731, 733.For example, the tabs 731, 733 could extend down from the side walls723, 725 of the hanger.

A hanger of this invention can include only one of the featuresdescribed above, or more than one such feature, or any combination ofsuch features. For example, one embodiment may have two sets of one ormore hooks on the hanger body, and these sets may be positioned atvarious locations on the hanger body. For example, the two sets of oneor more hooks could extend from different (adjacent or opposite) sidesof the hanger body or from other locations on the hanger body. Inanother embodiment, the two sets of hooks may be sized for receivingsupport rods of different diameters. In another embodiment, the hangermay have two or more hooks separated by a gap so that the hanger can besupported by a single nut on the support rod. In another embodiment, thegap may be sized and contoured so that the nut is movable in the gapbetween the un-locked and locked positions discussed above. In someembodiments, the hanger may be designed for supporting basket-wire cabletray. In other embodiments, the hanger may be designed to supportdifferent types of cable tray, or objects other than cable tray. Thehanger may be provided with any number of different extensions and bodystyles, depending on the particular application and type of object to besupported by the hanger.
